  1. 1. SOIL GROSS NITROGEN MINERALISATION AND FOREST GROWTH IN FOUR HEMIBOREAL FOREST STANDS IN SOUTHWEST SWEDEN

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Linnéa Eriksson; [2023-04-20]
    Keywords : soil C:N; forest production; 15N isotope dilution; gross N mineralisation; ammonium; soil carbon; soil nitrogen; root exudates; stoichiometric decomposition; boreal forests; priming; microbial C limitation;

    Abstract : Boreal and temperate forests together make up the largest terrestrial net C sink in the world. They take up carbon dioxide (CO2) from the atmosphere and store it in plant biomass and soil as they grow, making them crucial in mitigating global climate change. READ MORE

  3. 2. Underlying mechanisms behind nitrous oxide emissions in oilseed radish, Raphanus sativus var. oleiformis, and Phacelia tanacetifolia

    University essay from SLU/Dept. of Plant Breeding (from 130101)

    Author : Annika Swensson Källén; [2023]
    Keywords : nitrous oxide; glucosinolates; greenhouse gases; oilseed radish; Phacelia tanacetifolia; cover crops; labile C;

    Abstract : Greenhouse gases are a driving force of climate change and the annual greenhouse gas emissions were higher between 2010-2019 than any other time in human history (Skea et. al. 2022). READ MORE

  4. 3. Reindeer decrease soil carbon stocks and deplete labile soil carbon

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Josua Seitz; [2022]
    Keywords : Reindeer; SOC; soils; Finnland; 13C NMR;

    Abstract : Reindeer have been shown to alter boreal ecosystems by changing the vegetation cover and influencing belowground processes. By providing nutrients for plants and by exerting trampling stress on the field layer vegetation, reindeer induce shifts in the vegetation where ground-lichen are being replaced by evergreen shrubs.

  5. 4. Traits of peat- and upland-derived stream dissolved organic carbon in the permafrost region around Abisko, northern Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Nora Kainz; [2021]
    Keywords : physical geography; ecosystem analysis; permafrost degradation; DOC; DOC concentration; stable isotope carbon signature; DOC quality; DOC degradation; Atmospheric Sciences and Biogeochemical Cycles; Earth and Environmental Sciences;

    Abstract : Climate change-induced thawing of permafrost mobilizes previously frozen carbon of high potential reactivity, thereby, fuelling microbiological production of greenhouse gases. For this work, an analysis of the quantity, quality, and bioreactivity of DOC in streams from the Stordalen discontinuous permafrost catchment was carried out with stream water samples during the relatively warm summer of 2018.

  6. 5. Chemical degradation of PFAS using hydrogen peroxide and persulfate

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Jonathan Bannister; [2020]
    Keywords : PFOS; PFOA; PFBA; Hydrogen Peroxide; Persulfate; Degradation;

    Abstract : PFAS are a group of relatively newly discovered man-made pollutants. PFAS contains a C-F bond which is one of the strongest bonds in organic chemistry. Therefore, PFAS are not easily degradable and, once release into nature, are very persistent. READ MORE
